Running: The node is providing
all services that are appropriate for its role.

Stopping: The node is in
the process of stopping.

Stopped: The node is inactive.
Repair of a stopped node is prohibited.

Recovering: The node is
being recovered. When a node fails, the mirror node takes over the functions
of the failed node. The failed node tries to recover by using the data and
log records in main memory or on disk. The failed node uses the log records
from the mirror node to catch up with the transactions performed when it was
down. If recovery is successful, the node becomes active. If recovery fails,
the node state changes to repairing.

Repairing: The node is
being repaired. This operation reinitializes the node and copies the data
and log records from the mirror node. Repair is more time consuming than recovery.
